Django プロジェクトを、DreamHost がホストする運用 CentOS サーバーに移動することに行き詰まりました。Apache 2.2.23 と Python 2.6.6 がインストールされました。Django 1.4 と mod_wsgi 3.4 をインストールして構成しました。入力してApacheを再起動すると（Webアプリが完全に実行されることを期待しています）

sudo apachectl restart

/usr/local/apache/logs/ 内の Apache の error_log を調べると、次のように表示されます。

Pythonパスと関係があるように感じます。推測ですが。Python がクラッシュし続けているようです。

/home
  /myproject
    /public_html (server document root)
    /django_proj
      /myproject (django project root)
        settings.py
        other files and app directories for this django project
        /apache
          wsgi.py
          django.wsgi

httpd.conf の関連部分は次のとおりです。

<VirtualHost *:80>

    ServerName myproject.mysite.net
    ServerAdmin myemail@abc.com

    DocumentRoot /home/myproject/django_proj/myproject

    <Directory /home/myproject/django_proj/myproject>
    AllowOverride All
    Order allow,deny
    Allow from all
    </Directory>

    WSGIDaemonProcess myproject.mysite.net processes=1 threads=1 display-name=%{GROUP}
    WSGIProcessGroup myproject.mysite.net
    WSGIApplicationGroup %{GLOBAL}

    WSGIScriptAlias / /home/myproject/django_proj/myproject/apache/django.wsgi

    <Directory /home/myproject/django_proj/myproject/apache>
    Order allow,deny
    Allow from all
    </Directory>

</VirtualHost>

ここに私の wsgi.py があります:

import os

path = '/home/myproject/django_proj'
if path not in sys.path:
    sys.path.append(path)

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myproject.settings")

# This application object is used by the development server
# as well as any WSGI server configured to use this file.
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

ここに私のdjango.wsgiがあります：

def application(environ, start_response):
    status = '200 OK'
    output = 'Hello World!'

    response_headers = [('Content-type', 'text/plain'),
                        ('Content-Length', str(len(output)))]
    start_response(status, response_headers)

    return [output]

また、「mysite.net」ではなく「myproject.mysite.net」という URL としてホストしようとしています。私がそれを正しく行っているかどうかもわかりません。

実際の問題は何ですか？リクエストを行うときに実際にエラーが発生していますか。

ログ出力は完全に正常に見えます。すべての個別のプロセスは、Python が Apache の子ワーカー プロセスでも初期化されているためです。設定：

WSGIRestrictEmbedded On

彼らは立ち去り、1 つのプロセスだけを見る必要があります。

そのディレクティブに関する注意事項については、以下を参照してください。

http://blog.dscpl.com.au/2009/11/save-on-memory-with-modwsgi-30.html

ところで、「プロセス = 1 スレッド = 1」を使用するのは悪い選択のようです。一度に 1 つの要求しか処理できません。
